19. TSN
The TSN (Time-Sensitive Networking) Task Group (TG) is a part of the IEEE 802.1 Working Group (WG). The
charter of the TSN TG is to provide deterministic services through IEEE 802 networks (i.e., guaranteed packet
transport with bounded latency, low packet delay variation, and low packet loss).See
(TSN) Task Group | (ieee802.org)
Configuration
PTP Check
When using TAS and PSFP between network elements, there must exist a common global time reference
provided by PTP. When booting the device, it will take some time for a configured PTP application to get locked
to the common time reference. It may cause malfunctioning of TAS and PSFP if
config-change
is issued before
PTP time is in a Locked or Locking state. A function which can delay the issue of
config-change
until PTP is
Locked/Locking or a configurable time has passed, can be configured here.

Parameter descriptions
:
Procedure
: At the dropdown select how to ensure the PTP state:
Time only
: Use just the time parameter to ensure the PTP state.
Xxxxxx
: additional parameter(s) to be supplied.
Timeout
: Specify the maximal number of seconds to wait before a config_change is issued. The valid range is x
to y seconds. The default is 20 seconds.
PTPport
: Specify the PTP port to use for sensing PTP status. The valid range is x to y . The default is PTP Port 0.
